![]() ![]() Each actuator must still move within its own degree of freedom, as for a serial robot however in the parallel robot the off-axis flexibility of a joint is also constrained by the effect of the other chains. Errors in one chain's positioning are averaged in conjunction with the others, rather than being cumulative. SCARA, Stanford manipulators are typical examples of this category.Ī parallel manipulator is designed so that each chain is usually short, simple and can thus be rigid against unwanted movement, compared to a serial manipulator. Serial architectures a.k.a Serial manipulators are the most common industrial robots and they are designed as a series of links connected by motor-actuated joints that extend from a base to an end-effector. ![]() They are commonly used for machine tending in die-casting, plastic injection and extrusion, and for welding. They are one of the first robots to have been used in industrial applications. Spherical coordinate robots only have rotary joints. ![]() The compact effector design allows the robot to reach tight work-spaces without any loss of speed. They can move vertically and horizontally by sliding. The cylindrical coordinate robots are characterized by their rotary joint at the base and at least one prismatic joint connecting its links. In a 2-dimensional environment, three axes are sufficient, two for displacement and one for orientation. To be able to move and orient the effector organ in all directions, such a robot needs 6 axes (or degrees of freedom).
